MACHINE FOR- MOLDING CANDY PIPES AND OTHER ARTICLES.

Specification of Letters Patent.

Application filed March 1, 1910. Serial No. 546,659.

To all whom it may concern:

Be it known that I, GEORGE H. Fox, a citizen of the United States of America, residing at Bangor, in the county of Penobscot, in the State of Maine, have invented certain new and useful Improvements in Machines v for Molding Candy Pipes and other Articles, whereof the following is a specification.

This invention relates to a machine especially adapted for the manufacture of imitation smoking pipes made from candy.

The principal object of the invention is to provide a simple machine for the economical production of toy candies of the character indicated.

Figure 1 of the accompanying drawings represents a front elevation of one embodiment of this machine in open position. Fig. 2 represents a side elevation thereof, parts being broken out for better illustration. Fig. 3 represents in part a side elevation and in part a vertical transverse section thereof in closed position. Fig. 4 represents a vertical transverse section of the plunger part of the mold. Fig. 5 represents a perspective view of a toy pipe made by this machine. Fig. 6 represents a side elevation of another form of actuating mechanism in which the treadle lever is provided with a weighted arm for restoring it to normal position in lieu of the springs in the head for that purpose. Fig. 7 represents an end elevation of the hinged jaw provided with a cam of another form adapt-ed to restore the jaw to normal position whereby the spring for that purpose is dispensed with. Fig.8 represents a vertical section through one of the guideways of the head and an end elevation of a plunger carrier having its slide rod of a diameter to fit said guideway, the spring of the other construction being dispensed with and the guideway being practically closed by the slide rod whereby entrance of candy is prevented.

The same reference numbers indicate corresponding parts in all the figures, round numbers being used for the principal elements and intermediate numbers for the attributes thereof respectively.

The frame of this machine comprises a head 10 having a rearward horizontal flange 11, dependent hangers 20 and 25 extending downward from said head and preferably integral therewith and horizontal arms 30 and 35 extending rearward from the lower ends of said hangers and also preferably integral therewith. The head is provided on its front face with two ears or perforated lugs 12 and 13 and with a mold segment 15- preferably of brass, set in arecess or otherwise fixed in said face. Said front face is also provided with a flaring guide recess 14 tapered to a small orifice which extends through the side wall of said mold segment and which opens into the mold near the bottom thereof. The head 10 is also provided with two vertical holes or guideways 16 and 17 which extend through said head and are provided with internal shoulders 18 and 19.

The hangers 20 and are provided on their inner faces near their lower ends with side lugs 21 and 26 having guide holes 22 and 27 which are in alinement with the guide holes 16 and 17. The rearward arms 30 and are provided respectively at their inner ends with pintle holes 31 and 36 disposed opposite each other. These arms are also provided with another set of similar pintle holes 32 and 37.

The machine is secured to a bench or table A by means of bolts 23 and 24 passing through the horizontal flange 11 and through said table and by braces 28 and 29 connected at their outer ends by bolts 33 and 34 with the arms 30 and 35 and at their inner ends by bolts as 39 with the under side of said table.

A movable hinged jaw 40 swings on a pivot rod 41 supported in the lugs 12 and 13. This jaw is provided with a mold segment disposed in a recess in its inner face and adapted to coiiperate with the mold segment 15 in the head 10 and form therewith a mold open at the top and approximately in the shape of a bowl of a tobacco pipe. This mold segment may be of brass or other suitable material. This segment is also provided on its inner face with a lateral opening 42 adapted to register when the mold is closed with the orifice of the guide recess 14. The hinged jaw 40 is provided on its outer face with clamping screws 43 and 44 disposed one above the other. The hinged jaw is also provided on its opposite sides near its top with laterally projecting lugs 46 and 47 having rounded corners 48 and 49.

A plunger carrier 50 is supported at the upper end of a vertical sliding frame comprising rods and extending through the guideways 16 and 17 of the head 10 and Patented Dec. 13, 1910.

through the guide holes 22 and 2'7. The plunger carrier is provided with dependent lugs 51 and 52 adapted to engage the lateral lugs 4-6 and 47 of the hinged jaw 4L0 for tightly closing the hinged jaw and pressing the mold sections together. These dependent. lugs are preferably beveled at their lower ends at their inner faces to facilitate engagement with said lateral lugs.

A plunger constructed of brass or other suitable material is secured to the under side of the carrier 50 opposite the top opening of the mold. This plunger is preferably of a rounded acorn-like shape adapted to cooperate with the mold in forming the bowl of a pipe. This plunger is secured to the plunger carrier by any suitable means. In the form illustrated the plunger is provided with a threaded shank 56 which engages a screw-threaded hole in the center of the plunger 50, and with a flange 57 which is seated against the under face of the plunger carrier. This flange is of a diameter to fit within and practically close the mold and is provided on its under side with a groove 58 as shown in Fig. 4. On the depression of the plunger the flange enters the top of the mold and crowds down the soft 'andy and the groove 58 finishes the top of said )ipe bowl. forming a rounded surface there on. A nut engages the projecting end of the threaded shank 56 on the upper side of said carrier.

The slide rods 60 and 65 are screwthreaded near their lower ends and the rod 60 is provided with a pair of clampingnuts G2 and (53 and the rod 65 is provided with a pair of clamping nuts (57 and 68. The slide rods ($0 and 65 are fixed at their upper ends in socket holes of the plunger carrier 50 or otherwise secured thereto. Springs 61 and 6 surround said slide rods between the plunger carrier 50 and the shoulders 18 and 19 of the head 10. These springs or their equivalents serve to hold the plunger carrier normally in elevated position out of engagement with the hinged jaw 40. A cross head is secured to the lower ends of said rods by means of said nuts. This cross head is preferably provided with an antifriction roller 71.

An intermediate cross head is secured to said slide rods between the head 10 and the side lugs 21 and 26. This cross head is preferably adjustable on said slide rods by set screws '76 and T7 or other means and is preferably provided with an antifriction roller 78.

A cam arm connected with the hinged jaw 4:0 is engaged by the cross head 75 to operate said aw for closing the mold. The shank of this cam arm is provided with slots 81 and 82 and the clamping screws 43 and 44: pass through said slots and serve as means of attachment for said cam arm and render the same adjliistable on said jaw. The cam arm projects downward from said jaw, thence curves inward forming a curved cam face 85 and thence extends downward in a straight cam face 86. In the normally open position of the mold, the cross head 75 rests in the recessed or curved cam face 85 and thence as the slide frame descends said cross head rides over the inward curve and swings the hinged jaw 4:0 into closed position and thence rides down the straight cam face 86 during the downward movement of the plunger carrier and plunger. The spring 87 is connected at one end with the inner end of the cam arm and at the other end with a cross bar 88 spanning the space between the braces 28 and 29. This spring operates to swing the hinged jaw into open position and to normally hold it there.

A pintle 90 in the form of a rod or shaft is supported in the pintle holes 31 and 36 (or the pintle holes and 37) or other bearings of the horizontal arms 30 and 35. An actuating lever preferably a foot lever having a treadle 96 is supported on said pintle. T his lever is provided with an arm 97 which engages the cross head T0 of the sliding frame. This arm is preferably provided with a slot 98 so as to have a bearing against both the upper and under sides of said cross head or of its antifriction roller- In Fig. (3 the actuating mechanism shown in a modified form whereby the springs (51 and (56 of the head may be dispensed with. In this case the treadle lever 95 is provided preferably near its upper end with a lateral arm carrying a weight 111 adjustable thereon by means of a set screw 112 or otherwise. This weighted arm operates to swing the lever 95 into nor mal position and open the mold.

In Fig. 7 a supplemental arm 83 of a form similar to the cam arm 80 is secured at one end to the jaw l0 between it and the cam plate 80 by the same bolts which secare said plate 80 and at its opposite end the cam arm 83 is secured to the cam 80 by a bolt connection 89. This cam arm 83 has a cam surface Si and the space between said cam arms 80 and 83 forms a cam way in which cross head 75 travels during the swing of the actuating lever in either direction. hen the lever is swung forward, the slide rods 60 and ('35 are lifted carrying upward the erosshead 75 and the plate 83 engaged by said crosshead operates to open the mold. In this construction the spring 87 can be dispensed with. This supplemental cam spring or cam arm covers and protects the antifriction roller from particles of candy which might otherwise drop upon it.

In Fig. 8 the slide rods as (35 which support the plunger carrier are shown of a diameter adapted to fit and fill the guideways the carrier being unnecessary in view of the modifications just above described. The filling of the guideways by the slide rods prevents particles of candy from falling into and clogging said guideways.

A pipe 100 comprising a candy bowl 101 and a wooden pipe stem 102 is made by this machine.

The operation of the machine will now be described.

A candy composition known as hard candy in a warm plastic state is employed in making these articles. The mold sections 15 and 45 are preferably dusted with powdered sugar, fine flour or other suitable lubricant to prevent adhesion thereto of the candy material. The machine being in open position as shown in Figs. 1 and 2, a roll of such candy material "about one and one half inches long and three-fourths of an inch in diameter, more or less, is placed in one of the mold sections. The treadle lever 95 is then pushed backward. In this movement of the lever, the cam arm 97 engaging the cross head of the sliding frame 6065 swings downward and pulls down said frame. The intermediate cross head 7 5 on said frame engaging the cam arm 80 attached to the hinged jaw 40 swings said jaw into closed position and the mold section 15 shuts against the mold section 45 and presses said candy roll approximately into the form of a pipe bowl. One end of a pipe stem or sucker stick 102 is pushed through the flaring guide groove 14 of the head 10 and the lateral opening 1-2 of the hinged jaw into the mold, where it penetrates and is surrounded by the candy material. A further movement of the actuating lever 95 brings down the plunger carrier 50 and causes the plunger 55 thereon to enter the top of the mold and form the hollow space in said bowl. The plunger presses the candy material closely against the walls of the mold and around the end of the sucker stick and completes the shaping of the pipe bowl, the grooved flange 58 finishing the top edge thereof. The parts have then assumed the position shown in Fig. 3. The material quickly hardens, the foot lever is released, the mold opens by the action of the spring 87 or weighted arm or otherwise and the toy pipe is then removed from the mold.
